   I almost forgot this one..   
      
   If it had been Sarcomyxa, the gills at this stage would have been   
   yellowish, almost orange coloured, and the gills abruptly ending on a   
   yellow/greenish velvety stem. On Pleurotus, the gills continue   
   downwards. The real P. ostreatus is large, and usually rather dark   
   bluish grey. Other Pleurotus (one separate species grows mainly on   
   Populus, in the US newly described as P. populinus, probably the same   
   as the old P. salignus) are paler and smaller.   
   If you look at more pictures of Sarcomyxa, check the stem and how the   
   gills are ending there.
